Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0021] Example

[0022] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3As shown, this embodiment is a spliced ​​cyclone sand cleaner, including an upper tube 1 and a lower tube 2, a feed pipe 3 is connected to the side of the upper tube 1, a water outlet pipe 4 is connected to the top of the upper tube 1, the upper tube 1 is detachably connected to the lower tube 2, and the lower end of the lower tube 2 is sequentially connected to a sand storage tank 5 and a sand discharge pipe 18; it also includes a dredging mechanism 6, the dredging mechanism 6 includes an impeller 61, a rotating shaft 63, a bracket 62 and a blade 64, the bracket 62 is fixedly connected to the inner wall of the sand storage tank 5, the rotating shaft 63 passes through the bracket 62 and is rotatably connected thereto, the impeller 61 is arranged below the lower tube 2, and the impeller 61 is connected to the upper end of the rotating shaft 63, and the blade 64 is rotatably connected to the lower end of the rotating shaft 63, when the rotating shaft 63 When the blades 64 are driven to rotate, the blades 64 are expanded along the radial direction of the rotating shaft 63; the lower end of the rotating shaft 63 extends into the sand discharge pipe 18; specifically, the utility model arranges a sand storage tank 5 at the lower cylinder 2, most of the heavy sand enters it, and a small amount of water also enters below. When the sand cleaner is in operation, the sand in the sand discharge pipe 18 will be more than the sand in the storage tank. When the sand in the lower cylinder 2 is mixed with a certain amount of water to form a fluid flushing impeller 61, the drive will rotate, and then the rotating shaft 63 will drive the blades 64 to rotate. At a certain speed, the blades 64 will expand, and the stirring of the accumulated sand by the blades 64 will greatly reduce the risk of blockage, thereby playing a certain preventive effect.

[0023] Reference Figure 1 and Figure 2 As shown, the sand discharge pipe 18 in this embodiment is a bent pipe, and a dredging pipe 8 is connected to the bent part of the sand discharge pipe 18. A spiral rod 9 matching the diameter of the dredging pipe 8 is provided in the dredging pipe 8; it also includes a motor 13, a first pulley 11 is provided at one end of the motor 13, and a second pulley 10 is provided at one end of the spiral rod 9. A transmission belt 12 is wound between the first pulley 11 and the second pulley 10, and the spiral rod 9 is driven to rotate by the motor 13; specifically, when the impeller 61 is completely submerged in sand, the impeller 61 cannot be offset by the sand flow above, and then the speed of the impeller 61 is reduced or even stopped. In this case, the spiral rod 9 is driven by the motor 13 to move excess sand to the outside of the dredging pipe 8, so that the sand in the sand storage tank 5 continues to fall under the action of gravity, and the impeller 61 is exposed again to restore the dredging performance.

[0024] In addition, it should be noted that, since the size of the spiral rod 9 basically covers the diameter of the dredging pipe 8, when the spiral rod 9 does not rotate, sand will not leak out of the dredging pipe 8.

[0025] like Figure 2As shown, in order to realize automatic monitoring and dredging, the present embodiment further includes a monitoring component 7, which is arranged beside the blade 64, and the monitoring component 7 includes an elastic vibration sheet 71 and a sensor 72, the sensor 72 is arranged on the outer wall of the sand discharge pipe 18, one end of the blade 64 is arranged outside the sand discharge pipe 18, and the other end of the blade 64 is arranged inside the sand discharge pipe 18; specifically, the sensor 72 is electrically connected to the motor 13, and the sensor 72 uses a displacement sensor or a distance sensor to detect whether the elastic vibration sheet 71 is in a vibrating state or a certain vibration frequency, which can reflect the blockage situation. When the blockage of the sand discharge pipe 18 is relatively light, the blade 64 reaches a certain speed, and under the action of centrifugal force, the blade 64 can be radially expanded. The blade 64 in this state will touch the elastic vibration sheet 71, and the elastic vibration sheet 71 will vibrate, and the sensor 72 will recognize the signal; and when the impeller 61 stops rotating or the speed is relatively slow, the side reflects that there is a blockage situation, and then the motor 13 is powered on and started to discharge sand and dredge.

[0026] like Figure 3 As shown, the upper end wall of the sand storage tank 5 is connected to an auxiliary sand guide pipe 17, and the other end of the auxiliary sand guide pipe 17 is connected to the tail end of the sand discharge pipe 18. Specifically, when the sand content is high, a part of the sand that is about to submerge the impeller 61 can be discharged through the auxiliary sand guide pipe 17.

[0027] Reference Figure 1 As shown, the lower end wall of the lower cylinder 2 in this embodiment is connected with an overflow port 22; specifically, more water at the bottom can be discharged through the overflow port 22.

[0028] like Figure 1 As shown, in order to prevent the metal particles in the sand from damaging the impeller 61 and the blades 64, a plurality of magnetic suction strips 21 are arranged spirally around the inner wall of the lower cylinder 2; specifically, when the sand rotates close to the inner wall of the lower cylinder 2 under the action of centrifugation, the metal particles in the sand will be absorbed by the magnetic suction strips 21. When maintenance is required within a certain period of time, the upper cylinder 1 and the lower cylinder 2 can be separated, and the metal particles on the magnetic suction strips 21 can be cleaned.

[0029] The water discharged through the outlet pipe 4 still contains a small amount of sand. In order to further reduce the sand content, an inclined sand-isolating net 14 is provided in the outlet pipe 4, and the inner wall of the outlet pipe 4 is provided with a guide plate 15 inclined toward the sand-isolating net 14. The guide plate 15 is arranged close to the sand-isolating net 14. A connecting pipe 16 is provided between the outlet pipe 4 and the sand storage tank 5, and the connecting pipe 16 is arranged between the guide plate 15 and the sand-isolating net 14; specifically, after the sand-isolating net 14 isolates the sand, it will move down along the inclined sand-isolating net 14 to the gap between the guide plate 15 and the sand-isolating net 14 and flow into the connecting pipe 16, and then the connecting pipe 16 is transported to the sand storage tank 5. Under the action of the guide plate 15, most of the water flows out from the top of the sand-isolating net 14, and the action of the guide plate 15 makes the flow rate between it and the sand-isolating net 14 relatively slow.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
